Guide to the Whole Process of IVF in the United States: Key Steps from Preparation for Pregnancy to Medical Landing

In the early morning in Los Angeles, when the first beam of sunlight shone into the laboratory through the french window, embryologists had confirmed the expansion of the 37th blastocyst and wrote a note of "transplantable" in the electronic medical record. At this moment, Chinese families thousands of miles away have initiated their plans to travel to the United States, usually after 120-180 days have passed. The core reason why IVF in the United States attracts patients worldwide is "transparent regulations+iterative technology+controllable entire process". This article uses the dual perspectives of frontline medical consultants and laboratories to break down the 24 key nodes from domestic pregnancy preparation to overseas medical landing, helping Chinese families break down the "success rate" into executable schedules rather than just adjectives in advertising copy.

1、 Macro framework: parallel management of three timelines
1. Physiological axis: female menstrual calendar, male ejaculation calendar, synchronized endocrine homeostasis between the two. two Legal axis: Differentiated provisions, number of entries, and length of stay for assisted reproduction in the 50 states of the United States. three Financial axis: USD exchange rate, cycle package, emergency budget, credit card limit. Any axis with an error of more than 7 days will drag the "one-time travel" to "second entry", directly increasing the additional cost by 8% -12%.

2、 Domestic Pregnancy Preparation: Translating 'Want to Get Pregnant' into Medical Indicators
1. Female basic condition: AMH ≥ 1.2 ng/mL, FSH ≤ 10 IU/L, antral follicle count (AFC) ≥ 7, two of the three conditions must be met to enter the ovulation induction channel; If AMH<1.0, a mitochondrial support regimen of DHEA 25 mg Tid+Coenzyme Q10 600 mg Qd needs to be initiated 90 days in advance. two Male basic condition: sperm DNA fragmentation index (DFI) ≤ 15%. If it is>25%, varicocele screening and 30 day antioxidant intervention (vitamin E 400 IU+L-carnitine 2g) should be performed simultaneously. three Infection and immunity: TORCH, GBS, Mycoplasma, Ureaplasma, thyroid autoantibodies, antiphospholipid antibodies, NK cells, blocking antibodies, all must be completed 45 days before the start of the week. Any positive items must turn negative or fall below the laboratory threshold before traveling to the United States, otherwise the US clinic will require additional informed consent to be signed, delaying the transplant window. four Uterine cavity environment: Three dimensional ultrasound combined with saline infusion ultrasound (SIS) must be completed within 3-7 days after menstruation. If submucosal fibroids>2 cm, polyps>1 cm, or grade II adhesions in the uterine cavity are found, hysteroscopy should be performed first in China, and the patient can go to the United States for the second menstrual period after surgery to avoid waiting for 3-4 weeks for recovery in the United States. five Gene Carrying: Expanded Carrier Screening covers 301 autosomal recessive diseases, with slight differences in the mutual recognition list between Chinese and American laboratories. It is recommended to use the LDT version recommended by the CDC in the United States to avoid duplicate blood draws.

3、 Visa and Entry: Writing the "Medical Purpose" so that the visa officer can understand it at a glance
1. Visa type: B1/B2 is sufficient. If you plan to stay in the United States for more than 60 days, it is recommended to apply for multiple entries over 10 years and split the itinerary into two entries (15 days for egg retrieval and 12 days for transplantation) to reduce the risk of being questioned about immigration tendencies for a single stay that is too long. two Material package: clinic appointment letter, cost estimate sheet, doctor invitation letter, domestic real estate certificate, employer's employment certificate, bank statement for 6 months>RMB 500000. three Interview techniques: Replace "test tube" with "treatment plan" and "transplant" with "embryo transfer" to avoid sensitive words. four EVUS update: After visa approval, it is necessary to complete EVUS 72 hours before departure, otherwise check-in will not be possible. five Port of entry: LAX (Los Angeles) is the most friendly for medical travelers, CBP officials are familiar with the IVF process, and the average inquiry time for being taken into a small black house is 7 minutes, lower than SFO (San Francisco)'s 18 minutes.

4、 Clinic selection: Break down "success rate" into laboratory hard indicators
The CDC in the United States releases an annual Assisted Reproductive Technology Report, and the latest 2022 cycle data shows that there are only 12 clinics in the United States with a single embryo transfer live birth rate of ≥ 55% for patients under 35 years old, with 5 clinics in California. Based on the convenience of domestic patient transportation, Chinese language services, and laboratory quality control, the recommended tiers are as follows:
First tier: IFC IVF Center (INCINTA, Dr. James P. Lin, Torrance CA) and Reproductive Fertility Center (RFC, Dr. Susan Nasab, Corona CA) - both provide dedicated Chinese case managers, and the laboratory has passed CAP/CLAI dual certification with a blastocyst formation rate of ≥ 65%.
Second tier: HRC Fertility（Newport Beach）、SCRC（Santa Monica）、RSMC（San Diego）。
第三梯队：CCRM（Orange County）、UCLA Fertility、USC Fertility、Stanford Fertility、UCSD Fertility。

Selection logic: First look at the laboratory, then look at the doctor, and finally look at the price. Laboratory hard indicators: ① blastocyst formation rate ≥ 60%; ② The misdiagnosis rate of PGT-A is less than 2%; ③ The vitrification freezing recovery rate is ≥ 98%. Doctor's soft indicators: ① Annual consultation cycle>200 cases; ② The average age of patients is less than 37 years old; ③ Chinese communication or license translation.

5、 Remote first visit: Turning 13 hour time difference into 24-hour response
1. Appointment channel: Scan WeChat code → Fill in HIPAA authorization → Upload domestic inspection → Receive preliminary plan within 48 hours. two Video consultation: Zoom encryption, duration of 30 minutes, doctors share the screen synchronously to explain ultrasound and hormone six items, and a PDF version of the treatment roadmap will be issued 24 hours after the consultation. three Medication synchronization: American pharmacies can directly mail ovulation promoting drugs to China (FedEx cold chain), and domestic nurses provide video guidance for the first injection to avoid patients opening the package by themselves. four Legal documents: Remote signing of the "Treatment Consent Form", "Embryo Disposal Consent Form", and "Cryopreservation Agreement", Docusign electronic signature is equivalent to the US paper original, saving 5 days of international express delivery time.

6、 Travel to the United States for promotion: 15 day itinerary with particle size up to hours
D1: Arrive at LAX and check into the clinic agreement hotel (≤ 15 minutes' drive from the laboratory). Basic negative test will be conducted at 20:00 that evening. D2: Blood draw (E2, LH, P4) at 8:00 am, see the doctor at 9:30 am, initiate GnRH antagonist regimen, common medications: Gonal-f 300 IU+Menopur 150 IU, first injection at 8:00 pm. D5: Recheck E2, LH, P4+ultrasound and adjust the dosage. D7: If the dominant follicle is ≥ 14 mm, add Cetrotide 0.25 mg to suppress premature LH peak. D9: Ultrasound ≥ 3 follicles ≥ 17 mm, trigger that night: Ovidrel 250 μ g. D11: Egg retrieval surgery, IV anesthesia for 15 minutes, recovery within 1 hour after surgery, and male semen collection on the same day. D12: Fertilization report (ICSI routine), indicating the number of 2PNs. D16: Embryo report+PGT-A submission for testing. D17: Return to China or study in the United States to wait for transplantation.

7、 Embryo Laboratory: Making "Fertilized Eggs" into Traceable SKUs
1. Fertilization method: If the male's DFI is greater than 25%, direct ICSI can be used. If it is less than 15%, half IVF and half ICSI can be used, and comparative data should be kept. two Incubator: Time lapse EmbryoScope+low oxygen (5% O2), take photos every 10 minutes, AI algorithm automatically scores. three PGT-A sampling: 5-8 cells in the blastocyst stage trophoblast layer, laser incision of 7 μ m, 2-hour vitrification freezing after sampling. The sampled embryos are integrated with the QR code of the freezing tube to avoid embryo loss during cross-border transportation. four Report cycle: 7-10 days on NGS platform, with results divided into 3 levels: Euploid (euploid), Mosaic (chimeric), Aneuploid (non euploid). five Embryo storage: Liquid nitrogen tank temperature -196 ℃, 24-hour continuous monitoring, power outage endurance ≥ 7 days, monthly fee USD 75, credit card automatic deduction available.

8、 Palace preparation: Flip the 'land' to pH 7.4
1. Artificial cycle: Estrace 2 mg bid was initiated on domestic menstrual cycle D2, and endometrial thickness ≥ 8 mm and clear third line sign were rechecked on D14. Progesterone 100 mg Tid was added and transplanted 5 days after conversion. two Natural cycle: Ovulation monitoring+HCG triggering, progesterone 20 mg Bid for luteal support, suitable for patients with regular menstruation and type A endometrial blood flow. three Intrauterine infusion: Some patients may add hCG 500 IU or PRP 1 ml to improve endometrial receptivity, which needs to be completed 24 hours before transplantation in the United States. four Immune regulation: NK cells>12%, add Prednisone 5 mg Qd; TNF-α＞30 pg/ml， Add Adalimumab 40mg subcutaneous injection once, 2 weeks in advance.

9、 Transplant surgery: 180 seconds determines 10 months
1. Fasting for 2 hours before surgery, moderate bladder filling (ultrasound shows uterine axis). two Transplant catheter: Cook K-SOFT-5120, pre loaded with embryos and numbered by a doctor and embryologist. three Ultrasound guidance: At 3.5 MHz in the abdomen, confirm that the tip of the catheter is 1.0-1.5 cm away from the uterine floor, push out the embryo for 15 seconds, and let it stand for 30 seconds before withdrawing the catheter. four Postoperative observation: Lie in bed for 20 minutes, urinate immediately, and return to the hotel 2 hours later without absolute bed rest. five Luteal support: Progesterone oil 50 mg intramuscular injection+Estrace 6 mg oral administration+Prometrium 200 mg vaginal, triple pathway maintenance of serum P4>20 ng/ml.

10、 Pregnancy Testing and Early Pregnancy: Translating "Two Bars" into Numbers
On the 9th day after transplantation (D9), a blood draw of β - hCG ≥ 50 mIU/ml is considered the clinical pregnancy threshold. If it is less than 50, retesting is recommended within 48 hours, with a doubling time of 36-48 hours. two After transplantation, with D16 β - hCG ≥ 1200 and P4 ≥ 20 ng/ml, arrange for the first negative ultrasound to show the location of the gestational sac. three After transplantation, the fetal heart rate of D30 is 100-120 bpm, and the fetal heart rate of D45 is 140-160 bpm. If this standard is met, the patient can graduate and transfer to obstetrics. four Drug reduction: Reduce progesterone by 1/3 every 3 days after the fetal heart rate returns to normal, and stop taking the medication at 10 weeks to avoid sudden bleeding. five Timing for returning to China: It is recommended to wait until the fetal heart rate stabilizes before flying. For international flights, 20-30 mmHg medical elastic socks can be worn within 13 hours to prevent venous thrombosis.

11、 Cost panorama: Breaking down 'dollars' into Excel rows
(The following is the average package price for mainstream California clinics in 2024, which includes medical, pharmaceutical, laboratory, and anesthesia services, but does not include airfare and accommodation.)
Table 1 Single Cycle Cost Details (Unit: USD)

Single cycle total | 19250-23950 | If dual cycles are required, add 60%
Emergency budget: It is recommended to prepare an additional 15% for hysteroscopy PRP、 Immunoglobulin, secondary transplantation.

12、 Insurance and Refunds: Breaking Down 'Risk' into Hedgeable Financial Instruments
1. US medical insurance: Foreign patients can purchase short-term medical travel insurance (Cover America Gold), but IVF programs are considered fertility benefits and are usually exempt from liability; Unexpected complications (ovarian torsion, ectopic pregnancy rupture) can be compensated. two Clinic refund plan: Some clinics offer a 3-cycle package "live birth guarantee". If the clinical pregnancy is not reached, 70% will be refunded, but the female must meet 8 admission criteria such as BMI<30, AMH ≥ 1.0, and no uterine malformation. three Exchange rate hedging: A 5% fluctuation in the Chinese yuan against the US dollar would affect the total cost of 10000 yuan, which can be locked in a 6-month forward exchange rate with the bank to reduce the uncertainty caused by the expected interest rate cut by the Federal Reserve in 2025.

13、 Law and Ethics: Writing 'Cross State Differences' as Decision Trees
1. California: Allow couples and single women to undergo assisted reproduction, with birth certificates stating non genetic parents without the need for a court hearing. two Texas and Louisiana: There are religious background restrictions on embryo disposal, and it is not recommended for third parties to transport embryos. three New York: Starting from 2021, commercial assisted reproduction will be legal, but contracts will require independent lawyer review and an additional 3-week process will be added. four Embryo transportation: If cross state transportation is required, Cryoport dry liquid nitrogen tanks must be used, registered with the FDA, and an infectious disease test (HBV, HCV, HIV, HTLV, Syphilis) must be declared to the CDC 72 hours before transportation. Otherwise, the receiving laboratory will reject it. five Nationality by birth: According to the 14th Amendment to the United States Constitution, anyone born in the United States is granted citizenship. Parents can handle passport applications, but they need to make an appointment with the Federal Post Office in advance, which takes 4-6 weeks to process.

14、 Life support: Breaking down "medical tourism" into 15 details
1. Accommodation: The monthly rent for a two bedroom Airbnb in Torrance district is $3200. It takes 8 minutes to walk to the INCINTA clinic and includes a kitchen where you can boil Chinese medicine by yourself. two Transportation: LAX car rental company Alamo waives the surcharge for young drivers under the age of 25 for medical users, which is $260 per week including full insurance. three Diet: Whole Foods has a "pregnancy preparation" label, and DHEA and Q10 prices are 20% lower than those on Tmall Global in China. four Communication: T-Mobile Tourist Card costs $50, 30 days, 100 GB, supports WeChat high-definition video, and laboratory reports can be received in real-time. five Psychology: The Southern California Reproductive Psychology Association (SCRA) offers Chinese meditation courses, Zoom every Wednesday night for $45 each time, with FSA payment available.

15、 Common mistake list: Writing 'failed' as a checklist
Not arriving in the United States on the second day of menstruation, delayed by 5 days=wasting 1 month. two The domestic blood draw did not use international standard units, resulting in a retest of $300 by American doctors. three If the man abstains from ejaculation for more than 7 days, DFI will rebound, and ICSI+MACS will be temporarily changed, increasing by $1200. four Without Cryoport transportation, the embryos were temporarily stored at -80 ℃ in customs, resulting in an 8% decrease in recovery rate. five Choosing a red eye and connecting flight for the return flight, flying overnight after blood draw on the 9th day of transplantation, the doubling of β - hCG is not ideal, and it is impossible to determine whether it is due to embryonic factors or fatigue factors.

16、 Schedule Template: Cut 180 Days into Color Blocks
Day 1-30 (domestic purple): Physical examination → Visa → Remote first visit → Receiving medication. Days 31-60 (domestic green): DHEA+Q10 pretreatment → hysteroscopy (if any) → re examination of AMH. Days 61-90 (Chinese and American yellow): Notify the clinic on Day 1 of menstruation → Book a flight → Pay on Airbnb → Update EVUS. 91-105 days (orange in the United States): ovulation promotion → egg retrieval → fertilization → blastocyst → PGT-A. Days 106-150 (domestic blue): Waiting for report → Uterine cavity preparation → Medication for endometrial adjustment. 151-165 days (red in the United States): transplantation → pregnancy test → fetal heart rate → graduation. Days 166-180 (gray buffer): If a second transplant is required, you can re-enter through this window.

17、 Conclusion: Translating "Anxiety" into Action
The threshold for in vitro fertilization in the United States has never been technology, but rather "information synchronization" and "time granularity". When you break down 180 days into 24 executable nodes and mark each completion, anxiety is quantified as a progress bar. Next time, when the laboratory screen pops up with "Normal embryo, 46XX" or "46XY", you can accurately say which batch of incubator, which bottle of culture medium, and which uterine infusion it came from, instead of passively waiting for "luck". The true success rate from pregnancy preparation to medical implementation is to accumulate every 1% controllable factor until the 50% uncontrollable factors are covered. May this 4000 word guide become the first line in your Excel spreadsheet, rather than the last bookmark in your browser.
